Objective:

To highlight the role of ophthalmologists in the surveillance and response to the 2026 Andes virus outbreak, particularly concerning ocular manifestations.

Approach:

Overview of Hantavirus: Discusses the characteristics of hantaviruses, including Andes virus and its transmission, particularly through respiratory secretions.
Ocular Manifestations: Examines the ocular involvement in hantavirus infections, particularly focusing on the differences between Puumala virus and Andes virus.
Clinical Implications: Emphasizes the need for ophthalmologists to assess patients with suspected hantavirus infections and document findings to establish the ocular phenotype of Andes virus.

Key Findings:

Ocular manifestations of hantavirus infections are well-documented for Puumala virus but largely undefined for Andes virus.
The Andes virus outbreak has resulted in severe respiratory illness and confirmed person-to-person transmission.
Ophthalmologists can contribute to identifying ocular manifestations during the Andes virus outbreak.

Limitations:

Current understanding of ocular manifestations is primarily based on Puumala virus, which differs significantly from Andes virus in terms of disease severity and clinical presentation.
Published ophthalmic assessments of patients with hantavirus pulmonary syndrome (HPS) are lacking, particularly for Andes virus.

Conclusion:

Ophthalmologists have a critical role in the ongoing Andes virus outbreak, and their involvement can enhance the understanding of ocular manifestations associated with this pathogen.
